An eco-friendly methodology for the direct α-sulfanylation of ketones has been developed by using diaryl disulfides as sulfanyl source affording ketosulfides in good to excellent yields and high selectivity.
A facile and efficient protocol for the α-benzoyloxylation of β-keto sulfides is presented. This methodology provides a step-economical, mild and practical access to highly functionalized α-O-benzoyloxy substituted β-keto sulfides, including those with quaternary carbons, which are not easily obtained through currently available methods.
